Backplane Communication Velocity & Deterministic Networks
The 350-L-P0-G0-H-E-E-N-N-3E-D-N Feeder Protection Relay integrates dedicated Ethernet processing architecture to deliver high-velocity communication across EtherNet/IP and IEC 61850 deterministic networks. Fast Ethernet 10/100Base-T physical layer interfaces allow real-time event reporting, fault waveform extraction, and peer-to-peer GOOSE messaging with minimal frame processing latency. Onboard firmware flash compatibility ensures synchronized parameter updates and high I/O density scaling across networked distribution switchgear platforms.
Frequently Asked Questions
Q: Can the drawout unit be removed from the relay case without interrupting the primary Current Transformer (CT) secondary circuits?
A: Yes. The drawout case incorporates automatic internal CT shorting switches that engage before the physical terminal disconnection occurs, preventing dangerous open-circuit voltages on active CT loops.
Q: What power supply range is supported by the "H" control power code in this model configuration?
A: The high control power supply option accepts a universal input voltage range of 60 to 300 VDC or 84 to 264 VAC at 50/60 Hz.
Q: Does this relay model support IEC 61850 substation automation communication?
A: Yes. The "3E" option code provides a Fast Ethernet port operating with IEC 61850 protocol support alongside standard Modbus TCP/IP protocols.
Field Installation Guidelines
- Ensure all high-voltage feeder circuits and control power supplies are completely isolated and verified de-energized prior to installing or wiring the relay case.
- Mount the outer drawout case securely into the cutout panel using recommended mounting hardware to maintain enclosure integrity and mechanical grounding.
- Terminate phase and ground CT secondary wires using ring lugs, ensuring firm connection to the rear terminal blocks to maintain low-resistance contacts.
- Connect the main chassis protective earth ground terminal directly to the station grounding grid using a short, low-impedance copper conductor.
- Align the internal drawout relay module with the outer case guide tracks and push firmly inward until the latching levers lock fully into position.
